For about a month, while the watch did keep time, the second hand only moved 4 seconds at a time. In other words, it would no move each second, just in 4 second intervals. Now it is not keeping time, either the sec oind hand is stalled, or it will do one second movements about every 5-10 seconds. I'm pretty worried I now have a major (epxensive) problem. Bezels are always screwed tight, but I never take my watches off whether sleeping, exercise etc. Amy insights would be greatly apprciated.
